Induced Magnetism

Definition - What does Induced Magnetism mean?

Induced magnetism is the process used to induce magnetism in ordinary pieces of magnetic material by external influence. It is one of the ways used to turn magnetic materials such as iron and steel into magnets. When the unmagnetized magnetic materials are bought near or touch the pole of a strong or permanent magnet, they become magnets. This magnetic character is induced on the objects and it is removed when the permanent magnet is removed.

Petropedia explains Induced Magnetism

In induced magnetism, metallic objects are attracted by a strong or permanent magnet that magnetizes them.

For instance, when a permanent magnet is brought near a collection of paperclips, the paperclips become attached to each other and then to the permanent magnet. Every paperclip becomes a temporary magnet, and when the permanent magnet is removed they are no longer attached to each other. In this way, the magnetic property of the collection of paperclips was induced and was not part of their permanent character.
